If it was THAT important GM and all the other car co. would install them from the factory. The guys who sell them will tell you differently
Not true; cost drives these decisions more than importance.
It is just easier & cheaper to have the PCV system route the crap back into the engine and be done with it. THAT is why they are not installed OEM. Just one more thing for the owners to maintain and we all know how well most do that.
Just look inside your intake and you will change your mind... Not the throttle body, the actual manifold. It doesn't take a lot of oil to mess things up with carbon, hotspot coking, pre-ignition etc etc
